UConn started out against Stony Brook as cold as can be hitting only 1 of 12 shots to open the game.

The Huskies couldn’t have ended any hotter.

UConn made 8 of 11 3-pointers in the second half and rallied from a five-point halftime deficit as it held off Stony Brook 73-62 at Gampel Pavilion on Sunday night.

Shabazz Napier scored 19 points and Niels Giffey 15 to lead the No. 21 ranked Huskies. Omar Calhoun was also in double figures with 14 points for the Huskies.

The Huskies improved their non-conference record to 72-4 all-time at Gampel Pavilion and haven’t lost a non-conference game in Storrs since 2001. The Huskies also play part-time at the XL Center in Hartford.

That changed in the second half as the Huskies were hot from 3-point range and got Napier going. Napier took only two shots and had four points in the first half, but finished with 15 second half points including 3 of 5 from 3-point range including a 4-point play in the decisive second half run. Giffey added career-highs in points with 15 and rebounds eight and provided the spark the Huskies sorely needed.

UConn shot 63.6 percent in the second half .

The Huskies, at one point in the second half, scored eight straight baskets from 3-point range as it led by as many as 14 in the second half with 4:16 left to play.
